Social Behavior

4. A society is a group of animals of the same species living and working together in an organized way. Each member of the group has a certain role.
Like an ant colony – the queen lays eggs, workers do all the jobs for the society, and there are other ants that take care of the eggs specifically.
Some societies are organized by dominance. Wolves live in packs but there is a dominant female – this female controls the mating of the other females.
Societies

5. Territories are set up for feeding, mating, and raising young.
A territory is an area that an animal defends from other members of the same species.
Ownership of a territory happens in different ways. Songbirds sing, sea lions bellow, squirrels chatter, other animals leave a scent, and some patrol and attack those who enter their territory.
Territories have food, shelter, and potential mates.
